Have any of the testers played through the flaming thugs encounter yet? I was a bit concerned about balance for such an early encounter. Does it work OK, or is it too funky? Do you encounter them in a group, or do they spread out too much? Were they too hard or too easy?
Also, when you get to Baldur's Gate, let us know if you can actually complete the Quoningar quest. I think we stuck it in the inn west of the ducal palace; it'll want you to retrieve an item, but in typical fashion, I don't know that you can really find this item in the later stages of the game (I think there's at least one store that sells a single one). Does it turn hostile if you try to kill it (try hitting it with your fists)?
I'm especially interested in the ice island restoration. Make sure that Dezkiel doesn't show up in AR1009 (the normal labyrinth tunnels), as I'm not positive the code used to disable him works in BG1. Is the lighting in the area OK (the character colors should be reasonably appropriate, and infravision should work everywhere but the main entrance)? Is the height map OK (as the characters are walking, do they bounce up and down too much or have other weird movements)? Is the search reference OK (can they walk through walls or over water, or get too close to obstacles)? Make sure to keep a save from Ulgoth's Beard (before talking to Shandalar and getting sent to the island) so that any updates can be quickly tested.
